AI Technical Summary

Technical Problem

Existing fragrance beads have problems such as high-temperature melting leading to fragrance loss, high energy consumption during cooling, unstable product quality, and microbial mold growth during preparation. In addition, excessive moisture content leads to material softening and fragrance loss.

Method used

A combination of anionic surfactants, specific binders, fillers, and auxiliaries is used to extrude and granulate the product at 65℃-75℃ using an anhydrous preparation process, forming a fabric fragrance-retaining and stain-removing composition that is resistant to high temperatures, moisture, and quick-dissolving in cold water. Antibacterial and anti-mite agents are added to improve product stability.

Benefits of technology

It achieves product stability in high temperature and humid environments, avoids microbial contamination, and has excellent stain removal, long-lasting fragrance and antibacterial and anti-mite effects, while reducing energy consumption and fragrance loss.
